To all whom it may concern;

Be it known that I, HOWARD M. HAY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use-v ful Improvements in Sound-Deade-ning and Attaching Devices for Writing-Machines, of which the following is a specification.

The purpose of this invention is to provide sound deadening attaching means for securing typewriting machines to desks or' table tops in such manner that the machine may be readily released for any purpose, such as cleaning, or replaced, or the machine may be moved forwardly or rearwardly with respect to the desk or table without disturbing the connecting devices or lessening the effect of the sound deadening features. This permits the operator to adjust the maattachments are applied to a combination desk in which the writing inachineis made to disappear from view when not in use, the machine may be moved backward to permit the desk to close and will be securely held onits support when the latter is tilted or lowered.

In the accompanying drawing which illustrates my invention,Figure 1 is a plan view of devices. embodying my invention,

a typewriter machine, the latter being shown in horizontal section; Fig. 2 is a section taken on the line 22 of of Fig. 1; Fig. ,3

plan view of the same; and,

vices; Fig. sis a f f 1 0 one 0 tie Fig. 5 is a perspective view hooked guide bars.

Referring to the drawing, A indicates a suitable supporting bed, such as a top of a desk or table, and B indicates a "rectangular pad of sound deadening material, such as thick felt, which is laid upon the supporting bed. The frame C of the writing machine rests upon the pad B. As shown in Fig. 2, at the points where the rubberfeet 0 of the writing machine frame rest upon the pad B I the latter is provided with pockets 5 in which are inserted bags 7) containing granular material 6 such as sand. which serves as an additional sound deadening means and absorbs the vibrations of the machine, preventing their transmission to the supporting bed A One bag ofgranular material is arrangedunder each foot of the writing machine frame in the manner shown in Fig. 2.

The pad B, as shown in the drawing, has parallel sides and itre-sts loosely on the bed A so that when the machine is moved forward or rearward the padwill move with it.

Two strips D, of felt, are arranged at the sides of the pad Band upon the rear portions of these strips are arranged other shorter strips of felt d. These strips are secured together and to the bed A by screws 1 passing through sheet metal clips E having parts 6 pressed upwardly to form guideways or channels. Guidebars F are 3.1? ranged within these channels between the felt strips D and d. It will be seen that the guide bars 'restupon the strips D and that they are separated from the clips E by. the felt strips d so that there is no connection between the guide-bars and the bed A except through the strips of sound deadening material. These guide-bars are held firmly by the clips, butare yet free to move forwardly and rearwardly within the. uides when the machine is moved forwar Each guide bar has at least one upwardly turned hooked end, but they are preferably provided with two hooked ends 7 and f, as shown best in Fig. 5, the end f projecting higher than the end f, the purpose of this being to have the uide bars interchan cable for connection with latches held at di erent elevations on different forms of writing machines. The V latches are engaged by the hooks at the forward ends of the guide-bars, the hooks at the. rear ends serving as stops to limit the. forward movement of the machine. In the drawing, the frame of a Remington writing machine is shownand with this frame the latch G is supported in a lower position than on some other types of machine and therefore the guide-bars F are arranged with the shorter hookedends f at the front and with they-longer. hooked ends f at'the rear, although this would be reversed with some other types of machine.

The latches G, shown on each side of the machine, are similar in construction and interchangeable. Each latch comprises a basepiece- 2 which is clamped to one of the lower side bars 0 of the machine frame by a hook 3 passing over the side ba and provided with a clamping nut 3? beneath tje latch. To prevent the latch from twisting or turn 7 or, rearward.

' opening 6 are flat and a latch bar 9 is supported by and is movable upon the flat parts 8. Upwardly projecting ribs 10 extend along the front and rearv edges of the base 2 and these prevent longitudinal movement of the bar. The bar 9 is pressed by a spring 11 against a pair of shoulders, 12 and 12, adjacent the notches 7, which shoulders extend at right angles to the ribs 10, and a pair of tongues 13, integral with the base, extend over the bar 9 parallel with the parts 8 and serve to guide the bar. The sprlng l1 presses against the central portionof the bar, said spring being held in position by studs 14 and 15 on the base and bar respectively.

In applying the sound deadening and attaching devicesfthe latches G are secured to the frame of the machine as shown and-the hooked guide-bars F are arranged at the proper distance apart to engage the notches in the latches, and parallel with one another. The pad B is laid upon the support between the guide-bars and the writing machine is placed thereon so. that its feet Wlll rest upon the sand bagsb. When the machine is placed upon the pad the forward hooked ends of the guide-bars pass through the forward notches 7 in the latches, and the latch bars 9 spring under the shoulders on said hooked ends. The machine is then secured to the table or support. It is evident that if themachineis pulled forward or moved rearward the guide-bars will move with the machine, and asthe pad B is not secured to the support, it will also move forward and backward with the machine, which rests upon it. The sound deadening strips D are extended forward from the clips E in order that the guide-bars F may rest upon the strips D when the machine is moved forward. If the machine is placed upon a disappearing support,'the machine may be moved backwarduntil the forward hooked ends of the guide-bars strike the clips E, in order that the cover of the desk may close down without striking the machine, and when the support is tilted, the

machine will be held securely thereon by'the connections described.

In order to remove the machine for the purpose of cleaning the same, or for any other purpose, the operator presses the forward knobs -9=of the latch bars-9 inwardly, which releasesFthese bars from the hooks on machine movable thereon, sound deadening the guide-bars, as indicated in dotted lines in Fig. 4:, and simultaneously lifts the for ward end of the machine which carries the latches out of engagement with said hooked ends. The operation of removing the machine is accomplished with no more delay than would be required to lift the machine if the attachments were omitted and in replacing the machine it is only necessary to locate the proper notches in the latches over the forward hooks on the guide-bars and then lower the machine and it becomes automatically locked to its support.

It will be evident from an inspection of Fig. 4 that when one end of the latch bar 9 is moved inward, as indicated in dotted lines, the opposite end will fulcrum against the shoulder 12 and that thebar willfulcrum against the shoulder 12 when its op posite end is pressed inwardl By roviding two notches 7 in each latch and arranging the latch bar as described, the latches used on opposite sides of the machine may be and are alike in construction and interchangeable. 90
